摘　　要：以不同浓度的Cu^(2+)溶液为对象,采用基于农业废弃物制备的水热生物质炭微球吸附处理含Cu^(2+)重金属溶液,研究了吸附时间、溶液浓度、改性方式对重金属Cu^(2+)吸附效果的影响。比较两种不同的水热生物质炭微球对重金属Cu^(2+)的吸附效果,发现柠檬酸改性生物质炭微球吸附性能较优。Using Cu^(2+)solutions of different concentrations as objects,the hydrothermal biochar microspheres prepared based on agricultural wastes were used to adsorb and treat the Cu^(2+)heavy metal solutions.The experiment studied the influence of adsorption time,solution concentration,and modification method on the adsorption effect of heavy metal Cu^(2+).The research results show that,citric acid modified biochar has better microsphere adsorption performance by comparing the adsorption effects of two different hydrothermal biochar microspheres on Cu^(2+)of heavy metal.
